Abstract

A method and a corresponding device are provided for positioning a vehicle over the base unit of an inductive charging system. In particular, a charging station for wirelessly transmitting electric energy to a vehicle includes a base unit which is designed to generate an electromagnetic charging field for transmitting electric energy to the vehicle. The charging station has a receiving unit which is designed to receive a request signal from a transmitting unit of a vehicle. The request signal lies in any of a plurality of different frequency ranges. The receiving unit is further designed to determine a signal strength of the received request signal.
